1. Find the length of CD with endpoints C(-3, -4) and D(5, 5).

2. <1 and <2 are supplementary angles. m<1 is 4y + 7, and m<2 is 9y +4. Find m<2.

3. Ray GI bisects 9 years ago

Answer 1

1. Use the distance formula\[d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\]
2. Supplementary angles add up to 180°
\[4y+7+9y+4=180\]Solve for y, then solve for m<2.

3. Angles formed by a bisector are equal
\[x-3=2x-13\]
